The truth about all pear rootstock

[evilpaul]

Maybe I’m thinking of a different species, but the pear on hawthorn I’ve seen all had dramatic size differences at the graft union? Like the pear was six inches in diameter and the hawthorn was maybe four.

Aronia and cotoneaster are both dwarfing and pear compatible. We have a thread or two about both, with mixed results. My guerilla grafted pear on cotoneaster was either removed by people or deer. Probably the latter. The one on Aronia is still doing OK.

I believe a nurse branch left on the graft will prevent this from being so dramatic. But either way it’s a short lived tree (compared to a own roots pear especially)

I wonder what rootstock they use when producing trees in mass for the box stores, like Lowes.
I ran a search through AI and it told me that in Texas they most likely use Calleryana, which would be good news for me
